To go with the flow; to accept things you cannot change. <i>root: Henry Rollins spoken word, in which he refers to a sign above a Japanese hotel sink with the words "Be drinkable" (badly translated but meaning that it was safe to drink). He later uses it as an expression to be less apprehensive about unexpected or unpleasant things.</i>
"I am so pissed! My shoe got untied and I tripped over the lace in front of a hot girl!"
"Dude, be drinkable."
